A 64-year-old man tried to cross one of the busiest highways in the Washington region on foot Tuesday afternoon but was killed just before reaching the other side, authorities said.
The man was fatally struck by a car shortly after 4 p.m. on Interstate 395 near the Glebe Road exit  in Arlington, Virginia state police said.
The man, identified as Fekadu Ledi of Arlington, had crossed all of the southbound lanes of the Interstate, including the HOV lanes, the state police said. He then began to try to cross the northbound lanes of the highway.
He apparently crossed all the lanes but one.
Police said Ledi was struck in the far right lane and died at the scene.
It was not clear why he was on the interstate, which is one of the main traffic arteries in the Washington region and on the East Coast.

The driver of the striking vehicle, a four-door sedan, stayed at the scene, the Virginia State Police said.
